Magma that is rejected during a volcanic eruption forms igneous rocks?
Magma that is ejected during a volcanic eruption forms extrusive igneous rocks. They are also referred to as volcanic rocks.
Lava is magma that has reached the what in an eruption?
Lava is magma that has reached the surface of the earth in an eruption. When this cools down, it will form igneous rocks.
What does underground water do to a volcano?
Groundwater that comes in contact with magma or rocks heated by magma can boil into steam. If it boils quickly enough it can result in an explosion called a phreatic eruption.
What are the sequence of events leading to a volcanic eruption-?
During a volcanic eruption, magma moves in an upward direction towards the vent of a volcano. The type of eruption depends on the amount of silica and gas. After the eruption, magma touches the earth's surface and is classified as lava. Rocks and other debris in the volcano are forcefully pushed into the air. The rocks are called pyroclastic rocks. When the rocks touch earth, it turns into ash, dust, pummice or cinder.
Magma that is ejected during a volcanic eruption forms igneous rocks?
Yes, when magma is ejected onto the Earth's surface during a volcanic eruption, it cools and solidifies to form igneous rocks. These rocks can vary in composition and texture depending on the type of magma and how fast it cools.

What causes small earthquakes before a volcanic eruption?
The earthquakes are caused by the movement of magma underground and the breaking of rocks by that magma.
What is magma made of?
Magma is highly heated molten rock that comes to the surface of usually through volcanic eruption. Magma is usually found beneath the earth located near the earth's core and can sometimes contain crystals and gases.

What is matter such as magma and rocks forcibly expelled from a volcano vent during an eruption called?
Ejecta
What is the different between phreatic volcanic eruption and a strombolian eruption?
A Strombolian eruption is a type of magmatic eruption, meaning that molten rock actually erupts onto the surface. In a Stombolian eruption gasses trapped in the magma expand explosively, sending fountains of lava into the air. A phreatic eruption does not directly involve molten rock. Phreatic eruptions occur when water comes incontact with magma or hot rocks near magma and turns to steam, creating an explosion. Some ash may be ejected from these eruptions, but this is formed from the explosion blasting old rock rather than fresh magma.
What rock comes directly from magma?
Igneous rocks like basalt and granite are formed directly from magma cooling and solidifying.
What was obsidian before it was obsidian?
It was liquid rock (magma) which solidified after an extrusion or eruption. Crustal rocks can re-dissolve into magma during subduction of oceanic crust.
Where does the lava that erupts from Mount Etna come from?
The lava that erupts from Mount Etna comes from the magma chamber beneath the volcano. This magma is formed from the melting of rocks in the Earth's mantle due to high temperatures and pressure. When pressure builds up, the magma is forced up through the volcano's vent, resulting in an eruption.
